LIQUID-MEASURING .A-PPARATUS.

Specification of Letters Patent.

Patented Dec. 10, 1918 Application filed December 6. 1916. Serial No. 135.372.

T 0 all whom it may concern:

Be it known that- I, ()sv.\nnns VALDEMAR Kaiiox. a subject of the King of Denmark, residing at Bergen. Norway, have invented certain new and useful Improvements in Liquid-Measuring Apparatus; and I do hereby declare the. following to be'a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains tomake and use the same. reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, whichform a part of this specification.

My invention relates to means for measuring liquids and more especially for measuring liquids, the nature of which is such that the value of a certain 'volume varies according to the temperature and according to the varying quality or grade of the liquid.

'Such liquids are for instance petroleum. benzin, etc.

It is usual at present, at the sale of such liquids in larger quantities first. to weigh the cask or barrel, then fill it with liquid, then weigh it again and thereupon marking the barrel giving both the gross and the net weights. This procedure is very bothersome on account of varying grade, the volume of liquid measured for sale must vary in proportion.- My invention therefore relates to means whereby it is made possible during the delivery operation to regulate the volume ofthe measuring. vessel through .which the liquid passes. so that according to the temperature and to the grade of the liquid a varying quantity (by volume) of liquid is delivered to the different barrels.

To this end my invention consists in the combination with a closed measuring vessel of means to regulate the volume of the same and a hydromcter. and in the .tollowing I shall describe one manner of carrying out my invention, references being had to the accompanying drawing, which is a lateral the piston on view, partially in section of a measuring appa ratus.

In the drawing A. A rcpresent two measuring vessels. At the top and bottom these vessels by means of tln'ee-way-cocks ll. C connect with a supply pipe D and anoutlet l) respectively, 'lhcse cocks may be so eonn cctc.d with each other that while the top cock connects one measuring vessel with the supply pipe. the other one connects the other measuring vessel with the outlet and vice versa. E represents a thermometer mounted inside the supply pipe behind a window. 'l are air valves of any known design,

- .()n one of the measurin vessels a hvtemperature that the thermometer E in the supply pipe shows.

M is a piston, the position of which by means, of the screw spindle N may be regulated. thereby adjusting the volume of the measuring vessel. The piston carries a pointer O which indicates the position of a scale P. The scale P is indexed in accordance with the scale of the hydrometcr, so that when the operator places the piston pointeron the same index number as the one given by the-hydrometer the volume of the measuring vessel will be regulated to suit thegradc and the temperature of the. liquid just passing through the meas uri ng' apparatus.

There being two measuring vessels the apparatus may be worked very quickly. one vessel while the other is emptied into a barrel.

I claim:

1. In a liquid measuring apparatus in combination. a closed measuring vessel having inlet and outlet connections. means to regulate the exact volume of the measuring vesscl. an indicator showing the posit iou of said regulating means. a hydrmnelcr for indicating the specific. gravity of the liquid passed through the measuring vessel. the h vdrometcr and the volume indicator having their being filled from the supply pipe.

regulator is adjusted so that its indicator according to the quality of the material as 10 points on a mark which conforms with the determined by the sampler.
